Non-Fatal diagnostic/hardware
initialization faults
The module continues normal power-up, but an
entry is added to the Local Log table and the
RX3i CPU’s
Fault Table (if backplane
communications have been established).
Note the fault and
contact Customer

The module does not contain
hardware identity information
LED Fatal Error blink pattern, as described in

5.1.3
Transitioning to Firmware Update Mode
The module transitions to firmware update mode for any of the following reasons:
1.
WinLoader has commanded the module to enter firmware update mode. This is normal when a firmware
update has been initiated from WinLoader.
2.
The PNC001 does not have a valid firmware image at power-up. The PNC001 performs checks to
determine the firmware image is valid and has not been corrupted before it begins execution. If the
validation fails, firmware update mode is activated until a valid image has been stored.
For more information about firmware update mode and using WinLoader, please see Chapter 2,
